A SymbioCity in Malmö: From industrial area to city of tomorrow

A SymbioCity in Malmö: From industrial area to city of tomorrow | green streets | Scoop.it

A once decaying industrial area has transformed into an exciting, sustainable urban environment with a bright future. Sustainability inspired the architects behind this eco-city within a city. The Western Harbour now has its own energy supply and waste treatment system, very few cars – and plenty of satisfied residents.


Clean soil is the start of the eco-city: After decades of industrial and port activity, the soil at Western Harbour was so contaminated by oil residues that a clean-up was necessary before the area could be start its urban renewal.

Water: Surface water is managed via a network of open canals and dams. The system slows down rainwater flow and lush vegetation and vortex technology ensure favorable oxygen content and reduced algae growth. Green roofs on a significant number of the buildings add to the eco-friendly atmosphere.

Energy systems and eco-efficient buildings: The district is self-supporting in terms of energy use. A system powered by renewable energy produces heating, cooling and electricity for residents and is connected to the city's heating grid and power supply network.

Core of the energy system: The Aktern heat pump plant is the heart of the energy network and produces energy for heating and cooling. The energy is then stored seasonally in natural aquifers in wells. A local wind power plant provides the electricity needed to power the heat pumps and also supplies 1,000 apartments with electricity.

Solar cells on the roof:  Rooftops and walls are fitted with solar collectors, meeting 15 % of the the region's heating requirements. The system also includes solar panels.

Transportation: Planned as a standalone community with close access to goods and services, the Western Harbour has virtually no cars. Most residents walk to their homes. Bicycles and pedestrians have priority, and the area can be easily reached from the rest of Malmö on biogas buses operated by the local public transport company.

Building a Greener City

Building a Greener City | green streets | Scoop.it
With urban populations expected to soar, cities will have to be rethought from the ground up. Here's a look at bike lanes, micro wind turbines, pneumatic garbage collection—and other ways to make urban areas more environmentally friendly.

 

The goal: compact living environments that require less resources and that get the most out of the land, water and energy they do use.

Research in the Urban Transformation Towards Energy Efficient Cities

Research in the Urban Transformation Towards Energy Efficient Cities | green streets | Scoop.it

Among the most significant environmental challenges of our time are global climate change, excessive fossil fuel dependency of our cities and the growing demand for energy and materials – all major challenges of the 21st century and in the meantime some of the greatest problems facing humanity. Almost half the energy consumed is used in cities and urban built-up areas, and avoiding mistakes in the urban development at early stages will genuinely lead to more sustainable cities and less greenhouse gas emission. The Zero Waste SA Research Centre for Sustainable Design & Behaviour (sd+b) is conducting research in the City of Tomorrow and the role materials and energy will play in low carbon urban models. In this context, urban design and the fundamental principles of how we will shape our cities in future is increasingly recognised in the greenhouse debate; this is about time, as previously the debate has circled around active technology for ‘eco-buildings’, but less in holistic systems thinking for entire districts and neighbourhoods.
